Why is anode in a galvanic cell considered to be negative?

1.	Why is anode in a galvanic cell considered to be negative?
Answer» 1. According to IUPAC conventions, The electrode of a galvanic cell where de-electronation or oxidation takes place releasing electrons is called anode. Zn_(s) → \(Zn^{2+}_{(aq)}\) + 2e^- 2. The electrons released due to oxidation reaction are accumulated on the metal electrode surface charging it negatively. Hence anode in the galvanic cell is considered to be negative.

1. According to IUPAC conventions,

The electrode of a galvanic cell where de-electronation or oxidation takes place releasing electrons is called anode.

Zn_(s) → \(Zn^{2+}_{(aq)}\) + 2e^-

2. The electrons released due to oxidation reaction are accumulated on the metal electrode surface charging it negatively.

Hence anode in the galvanic cell is considered to be negative.
